impedance muffler meaning in English

阻抗复合消声器

Abstract : in this paper , we have had finite - calculation to dynamic structure according to the muffler drawings and the relation parameters . as we have received a disc impedance muffler model set at the entrance of lga fan by using the optimum design way before the muffler is made so that we can learn preliminary dynamic behavior . it has supplied effective ways
文摘:针对由最优化设计方法获得的lga风机进口安装的圆盘式阻性消声器模型，在未对消声器实物加工之前，根据消声器的图纸及有关数据进行了有限元动力计算，从而初步了解消声器的动态特性.为设计优良的消声器提供新的有效途径
